Brock-Doyle will join the Chime Communications-owned PR network in the newly created role of group CEO.

Having held discussions with a number of agency and in-house suitors, she told PRWeek she was attracted to Good Relations by the ‘refreshing and new’ set up of the Chime-owned group following the Bell Pottinger buy out last summer.

‘Driving international work will be part of the focus for me,' she explained. 'For example, the group’s CSR work has massive potential in other parts of the world, whether its Europe, Asia or elsewhere.’

A source at the group, which includes Good Relations and Harvard PR and consists of around 240 staff in nine countries, said it aims to double its size within the next three years.

Brock-Doyle, who has worked in comms and marketing for more than 25 years, will report to its chairman Kevin Murray.

She was named PRWeek’s PR Professional of the Year 2012 for her work in delivering the London 2012 Olympic and Paralympic Games, which was also awarded the PRWeek Campaign of the Year 2012.

In addition to overseeing Good Relations, Brock-Doyle will also be involved in CSM, the Chime-owned sports marketing division that is chaired by Lord Sebastian Coe.

She will also be involved in CSM, the recently launched sports division chaired by Sebastian Coe.

However, Brock-Doyle said that her forthcoming role would centre on wider brand communications.

‘It may not be as sports focused, but before I spent 14 or 15 years doing sport my career was in corporate, consumer and financial comms. The big challenge whether you’re promoting a sporting event or shampoo is building trust. Their vision attracted to me, and over the last few months they’ve created a group of established businesses and people based on a proposition around the power of good and helping clients build trusted brands.’

She added one of her primary tasks would be to create a group that was able to offer a ‘singular conversation’ with clients.

‘What we want to do is consolidate a range of exceptional businesses into something that all organisations can take advantage of. No longer do businesses want to take advice from lots of people.’

Brock-Doyle will assumed her role after attending an eight-week management course at Harvard University in the US after leaving her LOCOG job at the end of March.
